Kernel panic with telnet using 2.2.2 and f771 with 2.2.3

[Marc Dejardin]

Hello,

I have got kernel panics in telnet and f771 (according to log/messages) ...
I don't know if it could be usefull to anybody ?
I don't know really what to do with this.
But if one of the goal of linux is to be the most stable OS, perhaps it could be
interreting to understand why it happens.

Thanks for your help.
